Said wiper repairing device is characterized in that two pyramid-shape grooves ( 12 ) which facing each other are provided alongside two elongated surfaces of said frame ( 1 ), and said repairing means ( 2 ) consists of a first and second seats ( 21, 22 ), each having an abrasion element ( 211, 221 ) attached thereon fitted into said grooves ( 12 ), and a first and second springs ( 23, 24 ) provided vertically between said first and second seats ( 21, 22 ) for engaging both.

FIELD OF THE INVENTION

The present invention relates to a windshield wiper repairing device foran automobile.

DESCRIPTION OF PRIOR ART

A windshield wiper is very essential for visibility and safety.Defective windshield wipers can seriously compromise the driver's visionwhen road conditions are not favorable. A windshield wiper commonlycomposes of an arm, a frame and a rubber blade. Factors like sunlightcontaminants, oil and dirt cause the wiper blade to age and deteriorate.It's therefore recommended that the wiper blade should be replaced every6 to 12 months. The most commonly way is to replace the wiper assembly.The wiper assembly which includes a metal frame and the rubber blade canbe found and purchased easily in any automotive parts store, however,the price is varied depending the quality thereof and not economicalsince the frame is usually in a good state. A more economic way is toreplace the rubber blade by a blade refill. Although streaking and theinability to clear water from the windshield can be solved by abovemethods, the most efficient and economical method is to remove shallowslits or cracks occurred on the surface of the wiper blade. The presentinvention, therefore, is a wiper repairing device which has abrasivesurface to scrap off aging layer of the rubber blade and prolong theservice life thereof.

SUMMARY OF THE INVENTION

To achieve above-identified objective, a windshield wiper repairingdevice for an automobile is realized by having a hollow frame whose bothends engage with a cover respectively, and a repairing means isincorporated into said frame. A groove is provided respectively on twoelongated surfaces which face each other for receiving the wiper blade.Said repairing means composes of two seats with an abrasion elementattached respectively thereon. The two seats connected by two verticalsprings and are inserted into said grooves. The abrasion element can beselected from either a rough or a fine abrasive surface to providedifferent treatments to the aging wiper blade. As for repairing, thewiper blade is placed in the groove, and the edge of the blade ispressed against said abrasive surface by the force of springs whichconnect the seats. The repairing device is later operated by the user toperform a unidirectional movement for removing or scraping off shallowslits and cracks of the blade which is pressed against the abrasionsurface to restore proximately the wiper blade to its original state.Two springs ensure the abrading procedure being performed in balance,avoiding uneven surface being produced. Said wiper repairing device iseconomic and compact, ideally for placing in the trunk or glovebox of anautomobile.

DETAIL DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiment is described in detail according to theappended drawings hereinafter.

Referring to FIGS. 1 to 3, a windshield wiper repairing device comprisesof a hollow frame (1), two covers (11) attached to both ends of saidframe (1) and a set of repairing means (2) incorporated into said frame(1). Said wiper repairing device is characterized in that twopyramid-shape grooves (12) are provided at two elongated surfaces ofsaid frame (1) that face each other, and said repairing means (2)consists of a first and second seats (21, 22), each having an abrasionelement (211, 221) attached thereon fitted into said grooves (12), and afirst and second springs (23, 24) provided vertically between said firstand second seats (21, 22) for connecting the seats.

Each cover (11) has a U-shape guide way (111), thus when it couples withthe frame (1), the wiper blade (100) can be led into the groove (12)guided without difficulty through the guide way (111). The width of thegroove (12) is slightly wider than the wiper blade (100) to allow smoothinsertion, and able to secure the blade (100) within the groove (12).

The abrasion elements (211, 221) can have a rough abrasive surface or afine abrasive surface, or one element (211) has a rough surface andanother (221) with a fine surface. The rough surface can be provided bysandpaper having coarse grit size and the fine surface can be providedby sandpaper having fine grit size. The worn wiper blade (100) isrecommended to pass firstly the rough abrasive surface for removal ofslits or cracks, generating a new surface and then pass the fineabrasive surface to rub and smooth the surface further.

By installing both first and second springs (23, 24) vertically, thefirst and second seats (21, 22) are connected and supported by an evenforce to avoid creating jagged surface to the wiper blade (100).

Said frame (1) incorporates a spacing wall (13) for separating the innerarea thereof into two compartments from the center. The wall (13)increases the strength of the frame (1) for bearing external force. Anotch (131) is sized at an end of the wall (13) to retain said firstspring (23) and another notch (132) is sized at another end of the wall(13) to retain said second spring (24). The width of both notches (131,132) matches the diameter of both first and second springs (23, 24),thus said springs (23, 24) are allowed to move properly without affectedby said spacing wall (13).

Each of said first and second seats (21, 22) has two locating poles (25)for engaging respectively with an end of the springs (23, 24). Thelocating poles (25) facilitate procedure to assemble seats (21, 22) andsprings (23, 24) and maintain the springs (23, 24) in vertical fashionto avoid disengagement as they receive uneven pressure.

Each of said grooves (12) consists essentially of an elongated slit(121) provided on the surface of the frame (1) for receiving a wiperblade (100), an elongated slot (122) disposed within the frame (1) foraccommodating said first and second seats (21, 22), and a central groove(123) set between said slit (121) and slot (122) for receiving anelongated edge of the wiper blade. The cross section of the groove (12)shows a pyramid shape. The slot (122), which is the bottom, is thewidest and the slit (121) has the narrowest width to secure the wiperblade (100). The central groove (123) has a size between the slot (122)and slit (121) to provide space for the edge of the wiper blade (100)able to be bent angledly for abrasive purpose.

Said frame (1) has four curved edges (14) whose extreme end couples witha curved portion (112) of the cover (11). The curve design allows theframe (1) being attached with covers (11) more easily than a sharp edgeand meets ergonomic requirement as it won't cut user's palm when ishold.

Referring to FIGS. 4 to 6, the processes for repairing a windshieldwiper are described hereinafter:

-   -   Step 1. Wiper blade (100) is inserted into the groove (12) of        the wiper repairing device by passing through the guide way        (111). The blade (100) is secured by the slit (121) and the edge        thereof is accommodated within the central groove (123).    -   Step 2. Move the device in a unidirectional fashion along the        wiper blade (100). Said first and second springs (23, 24) within        the frame (1) apply a force to both first and second seat (21,        22), thus the edge of the blade (100) is pressed against the        seat (21) which has an abrasion element (211) (e.g. rough        abrasive surface).    -   Step 3. Repeat the steps 1 and 2 for 3 to 5 times consecutively        to remove aging and deteriorating surface of the wiper blade        (100).    -   Step 4. Extract the wiper blade (100) and insert it into the        groove (12) at an opposite end of the frame (1).    -   Step 5. Move the device in a unidirectional fashion along the        wiper blade (100). The edge of the blade (100) is now pressed        against the seat (22) which has an abrasion element (221) (e.g.        fine abrasive surface).    -   Step 6. Repeat the steps 4 and 5 for 3 to 5 times consecutively        to finish the surface until it is smooth and plane.
